Next if we fpllt length wife the Plant In the ftate 42, cutting thro’ 
the two Leaves and Bud, we fee the fame form and condition of the whole, 
only more grown : the Root is longer, and its Blea and Pith are in much 
larger quantity ; but the Bud is not yet at all advanced. See a magni- 
fied fection of this at P'ig. 47. The original ring of FleHi, which was 
the Embryo in the Farina, is extended in length, and covered, hut no- 
thing more : and we fill fee the feveral parts all rounding the end of 
the Root, and the Flelh, making an arch at the head of the Root, the 
point ^ from whence the Bud rifes. The Bud is little altered ; but we 
fee the Seed-Leaves juft in that part, begin to rile on Footflallcs. 
Last of all in the examination of this flate of the Plant, it wdll be pro- 
per to cut flrait down, in the fame manner, the entire and perfcdtly grown 
Seedling. 43. This will Hiew us the growth and ufe of the two firft 
Leaves ; and the diftindtion and connedtions of the feveral parts of the 
Plant. A fedtion of this kind is reprefented at Fig. 48. If we begin the 
examination at the point *, we there find the original termination of the 
annular Embryo fill preferved entire ; and as the wliole Plant above the 
ground, is to rife from this point, we fee a provifion for fuch a work : 
the Flefli extends to three or four times its ufual thicknefs in this part ; 
and the arch is formed entire, tho’ lefs vaulted than ufual in the lower fide 
of it. From the upper part and outer furface of this fwoln portion of the 
Flefh, arlfe all that is confpicuous in the Plant. From the outer furface 
of the Flelh of the Root continued in this fwelling, there is fent up on 
each fide a portion of its fubftance, which runs ftrait up the center of the 
Footfialk of each Seed-Leaf, 48, a. Within this are the Conic Clufiers, 
tho’ not eafily feen in the longitudinal fedtion, 48, b : and over thefe 
two fubfances run up regularly the Blea, and the two Rinds. 
We may judge of the importance of the Seminal Leaves of Plants by 
this conftrudtion. The permanent Radical Leaves of the Hellebore confift 
only of three fubftances, the inner Rind, and Blea with the Conic Ciufiers. 
But thel'c, ihort as their duration is to be, carry up alfo a part of the Flefh 
of the Plant. We have feen that this is fent up from the furface of the 
Tlefli of the Root ; and the VefiTels of the Conic Clufiers are formed with- 
in this, in each of the Footfialks; but the Blea and the two Rinds, 
are all fimply continued from thofe parts in the Root. A piece of a 
Footfialk more enlarged, is fhevvn at Fig. 4(). From the upper furface of 
the central part of the fwoln Flefh at the head of the Root, rifes the 
Bud for the future Plant, f.
